With the Zipp Ceramic Upgrade Kit you can make your Zipp wheels even faster. The high-quality bearings are made in Germany especially for Zipp. In order to keep manufacturing tolerances as low as possible, all work steps up to assembly take place under one roof. The highest quality stainless steel alloy available on the market for this area of intended use is used for the bearing tracks. In combination with the ceramic balls you get extremely smooth-running and durable ball bearings. The high durability of the materials used allows the bearing seals to be non-contact, which further reduces frictional resistance. The set consists of two 61903 ceramic hybrid ball bearings.
